Understanding Heron's Formula and Triangle Area

The video tutorial explains how to calculate the area of a triangle using two methods. Initially, it covers the common method of using the base and height, followed by an introduction to Heron's Formula, which is used when only the side lengths are known. The tutorial provides a step-by-step example of applying Heron's Formula, demonstrating its practical use in calculating the area of a triangle with given side lengths.

What is the formula for calculating the area of a triangle when the base and height are known?

• Base minus height

• Base plus height

• 1/2 times base times height

• Base times height
